What about my example? It gives incorrect output.

As a matter of fact, it gives correct output. Your code correctly detected that a floating point variable with the value (approximately) 42.993 does not contain an integral value.Originally Posted by Daved
Your error was in expecting that the series of calculations that produced the value would yield an integral value.
